339371 divided by 15 
Let's see how many times 15 fits into 339371.

Going ahead to step 1:
15 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 15

Advancing to step 2:
33 divided by 15 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 30 from 33 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 15

Step 3:
When dividing 39 by 15, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 30 from 39 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 15

Let's proceed to step 4:
15 goes into 93 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we subtract 90 from 93, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 15

On to step 5:
When dividing 37 by 15, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2262.0
Deduct 30 from 37 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 15

Advancing to step 6:
71 divided by 15 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 22624.0
Deduct 60 from 71 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 22624.7
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 22624.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 22624.733
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 22624.733 and a remainder of 0.0005.
